Wonder if anyone checked if the nozzles match ?
There is a NATO standard. STANAG 7191, but SA are not in NATO.
Saudi Arabia fly F15 and Eurofighter. I can't find any info on who uses that standard, or not. But the current edition appears to be from 2022. I found an article saying a Brit voyager refueled Qatari jets, but oddly enough, the nearest info I can find on my limited web, is cos of Palas--t- Acon and when they damaged the UK tankers.
Now, before anyone says I am nit-picking and trying to find problems for whatever reason
The Brit tankers do not mate with Israeli Jets. So they are not all compatible.
Despite claims, British tankers cannot refuel Israeli jets (ukdefencejournal.org.uk)
From that linked article -
"The RAF operates the Voyager KC2 and KC3, which use the probe-and-drogue method of aerial refuelling. This system involves a flexible hose with a drogue basket that extends from the tanker. Receiving aircraft must be fitted with a refuelling probe that connects with the drogue to take on fuel. This method is standard across the UK and NATO for aircraft such as the Typhoon, F-35B, and other compatible platforms.
Israeli fighter aircraft, including the F-15 and F-16, use the flying boom method. This involves a rigid, steerable boom extending from the tanker aircraft, which connects to a receptacle on the receiving jet. Israel uses converted Boeing 707s and has recently begun operating KC-46 tankers, both of which are equipped with flying boom systems.
The two systems are not interchangeable. RAF Voyagers do not have booms and cannot be modified to carry them without extensive structural redesign. It is not a matter of operational secrecy or political alignment. It is a basic question of engineering. A Voyager cannot refuel an Israeli F-15 any more than a diesel pump can refuel a petrol engine."
Going by that, I would say it seems the UK tankers will be ok for Saudi Typhoons, but not their F15. So then it comes down to what ammo the different jets carry.
The UK helping SA drop bombs looks to me, as if that means Euro bombs that Euro Jets carry. So, no money in it for Trump.
